Totali whom it mayconcern.- -,Be itl known that I, FRIEDRICH'GRSO'HE, manufacturer, a subjectof theGrand Duke vof SaXe-Weimar-Eisenach, residing at Ilme- "a s ecification.

.'eecting the quick return of t thread or column in maximum thermometers.

nau, Grand Duchy of S'aXe-Weimar-Eisenach, Germany, have invented certain new and useful Improvements in Ap aratus for Shaking Thermometers, 'of Whicll 4 hisinventionrelates to an apparatus for Figure 1 is a side view, partly in section,

l owing' one form of the invention. Fig. 2 is similar view illustrating a modiiic'ation, and

ig. 3 also asimilar view illustrating a still further modification.

The apparatus .consists of a rodor tube t'o the iront endv of. which is secured the thermometer, the said rod being throughout` or lin part oi its len th elastic in such manner I that 4When the rov is, moved in jerksl or Yinthe vertical plane vthe vibrations thus vproduced are transmitted Vto the front portion. of the same in the form' ofinultipliedvibrations or `trepidations.which'act on the mercury column so that the latter is driven back the mercury-cup.

It is preferable, to make the protective socket or casing in which the thermometer is* inclosed when. it is not in use elastic .both of its portions. If, this rotective socket'is made'of elastic rubber, `its elasticitywill'be sufficient lin order to convert the striking movement into multiplied vibrations when i multiplied vibrations or 'trepidation's'-' The.

\ into a protective casing b, consisting of a rub- Whole rotective socket or casing could also be ma eof helically-Wound elastic steel Wire. i -Such a construction oir apparatus according to this ,invention is illustrated, by way of example, inthe accompanying drawings. 4

ber. tul closed at the back end and containing in front. the' screw-union c for fixing the thermometer. When this sockety is given a strong jerk in the vertical plane, the suitably y thickrotective socket .vibrates and trans-vv mits t eivibration given by the hand movement, multiplied many times, to the thermometer. .l l Fig.v 2 shows a protective casing or socket of metal, the one. portion d of which'serves for screwing in the thermometer and is connected -tot e other closed tubular portion by a helical spring f.

What I claim is 1. An'ap aratus for shaking thermometersl to feiiect t e quick return of the mercury column, comprising an elastic socket mem-' ber, 'and means for securing ya .thermometer therein.

toeect t umn, 'comprising ahandle l.affording atv one end an elastic portion, and means for securto'effect 't e quickreturn oi t fe. mercury column, 4comprising a handle affording at its louter end anelastic portion, and a coupling -member secured in said elastic ortion an 4 75 2. An apparatusior shakin thermometers e quick return of t e mercury col` adapted to have the end of the t ermonieter secured therein.`

4. An a paratus for shakin thermometersI to eiiect t e quick return of t emercury column, comprising `an elastic handle, and means'for securinga thermometerin one end thereof.

5, An apparatus for shakin thermometers i to effect the quick return oi t e mercury col-- umri, comprising a socket member formed of a continuous helieallly-wound Wire, and

means for securing a thermometer in one end of said socket member.
